Before use, soft jaws must be machined (bored) in situ on the chuck to compensate for mounting tolerances and achieve maximum concentricity — a soft jaw machined in situ exceeds any standard hardened jaw in precision.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eAre these Ø 250 mm jaws compatible with my chuck?\u003c\/summary\u003e\n\u003cp\u003ePS3\/PS4 jaws are designed for 3 or 4-jaw chucks with PS-type mounting — check compatibility with your chuck before purchasing. The Ø 250 mm diameter indicates the chuck size for which the jaws are designed. Also check the number of fixing bolts on your chuck.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan monobloc jaws be reversed for external gripping?\u003c\/summary\u003e\n\u003cp\u003eNo — monobloc jaws are not reversible. For external gripping (clamping from the outside of the workpiece), reversible top jaws from the TJ or DTJ series are needed. Monobloc jaws only exist in an internal gripping version or an external gripping version — check the type before purchasing.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDelivery times?\u003c\/summary\u003e\n\u003cp\u003eOriginal spare parts available with 3–5 working days shipping.
